Local Testing
The preferred way of locally testing the role is to use Docker and molecule (v2.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system. We are using tox to simplify process of testing on multiple ansible versions. To install tox execute:
pip install tox
To run tests on all ansible versions (WARNING: this can take some time)
tox
To run a custom molecule command on custom environment with only default test scenario:
tox -e py27-ansible25 -- molecule test -s default
For more information about molecule go to their docs.
If you would like to run tests on remote docker host just specify DOCKER_HOST variable before running tox tests.
